Which of the following are symptoms of hypoglycemia?
A) tachycardia and trembling
B) bradycardia and diaphoresis
C) anxiety and flushed, dry skin
D) flushed, dry skin and tachycardiaAnswerA) tachycardia and trembling
When the blood glucose drops, sympathetic stimulation occurs. Symptoms are masked for a patient
who is receiving beta-adrenergic blocker drugs. Flushed, dry skin is a sign of hyperglycemia.
Which of the following is TRUE for a patient who has had a right sided stroke and develops increased
ICP?
A) the pupils will change before the level of consciousness does, there will be right sided paralysis,
the eyes will be deviated to the left, and there will be a left pupil change.
B) the pupils will change before the level of consciousness does, there will be left-sided paralysis, the
eyes will be deviated to the right, and there will be a right pupil change
C) The level of consciousness will change before there will be pupil changes, there will be right sided
paralysis, the eyes will be deviated to the left, and there will be a left pupil change
D) The level of consciousness will change before there will be pupil changes, there will be left sided
paralysis, the eyes will be deviated to the right, and there will be a right pupil changeAnswerD) The
level of consciousness will change before there will be pupil changes, there will be left sided
paralysis, the eyes will be deviated to the right, and there will be a right pupil change
Higher brain centers (cerebral cortex) are the first to be affected by increased ICP. therefore, the level
of consciousness is the first sign (the one exception to that rule is epidural hematoma). pupil changes
are ipsilateral (same side as the injury) due to compression of cranial nerve III against the
transtentorial notch. motor changes are contra lateral (opposite side of the injury) due to motor fiber
crossing in the brain stem
a patient status post head trauma has an ICP of 32mmHg. which of the following interventions is
contraindicated for this patient?
A) provide enteral feeding via a nasal tube
B) elevate the head of bed 30-45 degrees
C) maintain a MAP of 50-60
, D) avoid hypotonic IV solitonsAnswerC) maintain a MAP of 50-60
the patient has an elevated ICP, and the patient requires a MAP greater than 50-60 in order to
maintain cerebral perfusion pressure and prevent brain ischemia. the remaining interventions listed
in choices A B and D are indicated for a patient with elevated ICP.
which of the following is associated with mitral regurgitation?
A) systolic murmur, sinus bradycardia
B) diastolic murmur, heart failure
C) systolic murmur, inferior wall myocardial infarction
D) diastolic murmur, complete heart blockAnswerC) systolic murmur, interior wall myocardial
infarction
inferior wall MI may result in ischemia and dysfunction (regurgitation) of the mitral valve. the mitral
valve is closed during systole (left ventricular ejection). a murmur is produced when the mitral valve
is not fully closed during systole.
a nurse knows that research supports a patient having unrestricted access to his or her designated
support person (according to the patient's wishes). however, the nurse's unit restricts all patient
visitors to set times. the nurse's best response would be to:
A) gather the facts and propose a policy change to the manager for the unit
B) tell patients/visitors that the unit's policy is outdated but there is nothing that can be done about
it
C) continue to follow the unit policy
D) complain to colleagues about the outdated policy.AnswerA) gather the facts and propose a policy
change to the manager for the unit.
the AACN synergy model supports patient advocacy. unrestricted access to a designated support
person (according to the patient's wishes) is an evidence based practice that is included in the family
presence: visitation in the adult ICU AACN practice alert.
nitrate therapy is indicated for the treatment of unstable angina and acute heart failure because it:
A) decrease preload and increases myocardial O2 demand
B) increases preload and increases myocardial O2 demand
C) increases preload and decreased myocardial O2 demand
D) decreases preload and decreases myocardial O2 demandAnswerD) decreases preload and
decreases myocardial O2 demand
